| 1995 | £77,200 | £167,821 | 190 |
In cash terms the typical AL4 9 home went from £77,200 in 1995 to £523,800 in 2026, roughly 7 times the price. Even after inflation that is a real rise of about 212%: homes here genuinely became dearer, not merely more expensive on paper. In inflation-adjusted terms the high-water mark was 2018. The market now sits about 21% below it, so a peak-time purchase has yet to recover its real value.
Year-on-year change in the AL4 9 median
Each bar is the change on the year before, in cash. The zero line is the boundary between rising and falling.
The strongest year on record here is 2002 (+27.8% on the year before); the weakest, 2009 (−7.2%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
What AL4 9 has returned, per year
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | −2.1% | −4.4% |
| 5 years (since 2021) | +0.8% | −3.8% |
| 10 years (since 2016) | +2.1% | −1.3% |
| 20 years (since 2006) | +4.3% | +1.4% |
The table annualises median growth over each period, with the real column deflated by ONS CPIH. Smoothing hides the cycle (see the chart above for it), and none of this forecasts: it is the record.
Transaction volumes
Sales per year, counted
Each bar is a year's recorded sales. 2008's dip is the financial crisis, and the newest bar always grows for a while as late registrations arrive.
The register shows 50 AL4 9 sales across the most recent twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 250 sales a year before the financial crisis and 137 a year over the last five. Price without volume misleads: a median built on few sales jumps around, and one street can tilt it. Keep in mind too that the latest year is still filling in, since sales reach the register weeks or months after completion.
What tenants pay around AL4 9
The local authority for AL4 9 is St Albans, and its ONS average private rent currently stands at £1,925 a month (May 2026 figures). A one-bed averages £1,266 a month here and a four-or-more-bed £2,897, so size does most of the work in setting the rent.
Average monthly rent by size, St Albans
ONS Price Index of Private Rents, May 2026.
Set against the £523,800 median sold price, £1,925 a month is £23,100 a year, a gross yield of 4.4%: gross, before letting costs, voids, maintenance and tax, so a ceiling rather than a promise. Rents are published at local-authority level, so nearby districts in the same authority share these figures.
How AL4 9 trades
This is a thin market: 50 sales in the last twelve months of data. With that few transactions, one street selling well (or one block of cheap transfers) can move the median, so read the year lines as a range rather than a verdict. Against the AL4 district median, AL4 9 sits 18% lower, marking it as a cheaper pocket of the district.

Bedroom by bedroom: AL prices by size
Real sold prices by size across the AL area, straight from the Land Registry record. How much a size step costs is a local fact: the third-bedroom premium runs from about a quarter to nearly four fifths depending on the area, and national rules of thumb miss it.
